Distribution of birds is dynamic. Understanding, documentation and appropriate use of new records are essential, especially when managing threatened species. Here we present novel data regarding new distributional records for 17 bird species along the Amazonian slopes of the eastern Ecuadorian Andes. The new records fill gaps on our knowledge in the distribution, both in latitude and altitude.

We report two bird species with pigment anomalies, which were seen in Cali, Colombia in 2020. The individuals were, a female Shiny Cowbird (Molothrus bonariensis) with partial leucism, a female Ruddy Ground-Dove (Columbia talpacoti) with partial leucism and a young nestling of the same species, with albinism. The records reported here are the first of partial leucism and albinism for Columbia talpacoti and partial leucism for Molothrus bonariensis in Colombia.

Accurate maps of species ranges are essential to inform conservation, but time-consuming to produce and update. Given the pace of change of knowledge about species distributions and shifts in ranges under climate change and land use, a need exists for timely mapping approaches that enable batch processing employing widely available data. We develop a systematic approach of batch-processing range maps and derived Area of Habitat maps for terrestrial bird species with published ranges below 125,000 km2 in Central and South America. (Area of Habitat is the habitat available to a species within its range.) We combine existing range maps with the rapidly expanding crowd-sourced eBird data of presences and absences from frequently surveyed locations, plus readily accessible, high resolution satellite data on forest cover and elevation to map the Area of Habitat available to each species. Users can interrogate the maps produced to see details of the observations that contributed to the ranges. Previous estimates of Areas of Habitat were constrained within the published ranges and thus were, by definition, smaller—typically about 30%. This reflects how little habitat within suitable elevation ranges exists within the published ranges. Our results show that on average, Areas of Habitat are 12% larger than published ranges, reflecting the often-considerable extent that eBird records expand the known distributions of species. Interestingly, there are substantial differences between threatened and non-threatened species. Some 40% of Critically Endangered, 43% of Endangered, and 55% of Vulnerable species have Areas of Habitat larger than their published ranges, compared with 31% for Near Threatened and Least Concern species. The important finding for conservation is that threatened species are generally more widespread than previously estimated.

We monitored reptile and bird roadkills in Cerrado–Pantanal landscapes along the Campo Grande to Corumbá highway BR-262. We describe species distribution in different landscape zones, including the first geographic record for Hydrodynastes bicinctus Herrmann, 1804 in the Pantanal basin. The roadkill occurrence of Spizaetus melanoleucus (Vieillot, 1816) is an outstanding record. We recorded 930 individuals belonging to 29 reptile and 47 bird species; 20 of these species are new roadkill records in Brazil. The 8 new records of reptile species include Eunectes notaeus Cope, 1862, Bothrops mattogrossensis Amaral,1925, Dracaena paraguayensis Amaral,1950 and H. bicinctus; and 12 new records of bird species include S. melanoleucus, Heterospizias meridionalis Latham, 1790, Urubitinga urubitinga (Gmelin, 1788), Pulsatrix perspicillata (Latham, 1790), Aramus guarauna (Linnaeus, 1766), and Jabiru mycteria (Lichtenstein, 1819). Richness of road-killed species on the BR-262 highway seemed to be high, reinforcing concerns about wildlife-vehicle collisions where these accidents occur, as they lead to long term and chronic impacts on wildlife and road safety in the Pantanal region.

Abstract The hippoboscids are cosmopolitan permanent obligate hematophagous ectoparasites of birds, domestic and wild mammals and, occasionally, humans. Some species may act as vectors or hosts of etiological pathogenic agents. The aims of this study were to report on the first cases of Hippoboscidae in Crax blumenbachii and Parabuteo unicinctus; to provide new reports from Brazil on Tyto furcata and Asio stygius parasitized by Icosta americana; to report on individuals of Bubo virginianus, Falco sparverius and Accipiter striatus parasitized by genera Ornithoctona; and to provide new reports on parasitism of O. erythrocephala in the state of Rio Grande do Sul. The birds of prey and C. blumenbachii were attended at a rehabilitation center in Porto Alegre and at a veterinary hospital in Cruz Alta. These new records demonstrate the huge gap that exists regarding studies on avian ectoparasites and highlight potential vectors of hemoparasites for the bird species studied.

New records and possible range extensions are reported on 45 bird species (ca 25% of the 167 species recorded during surveys) in the Bophirima district of the North-West Province, South Africa. The findings were compared with data in The Atlas of Southern African Birds. The main reasons for these new records may be ascribed to the low number of visits during the atlas project, higher precipitation during the time of our observations versus that of the atlas project, and possibly an increased suitability of the area for some bird species due to human habitation. These new records also provide additional information that may be useful in conservation planning, especially in arid areas. Heuningvlei Pan in particular, should be considered for additional conservation measures.

This study contributes to the knowledge of central European clitellates by creating a check-list of Oligochaeta (sensu oligochaetous Clitellata; Erséus 2005) of the Czech Republic, exclusive of taxa in the family Enchytraeidae. In total, 95 aquatic oligochaete species representing 43 genera are reported for the Czech Republic. Rare species are highlighted and associated with the categories for threatened species as outlined by the International Union for the Conservation of Nature. The first records of Trichodrilus strandi Hrabě, 1936, Pristina jenkinae (Stephenson, 1931), Pristina osborni (Walton, 1906), Rhyacodrilus subterraneus Hrabě, 1963, Aulodrilus limnobius Bretscher, 1899, and Aulodrilus pigueti Kowalewski, 1914 in the Czech Republic are presented. Their ecology, morphology, and distribution are discussed.

Previously known from two specimens, Kaempfer's Tody-tyrant Hemitriccus kaempferi is a globally threatened species endemic to the southern Brazil Atlantic Forest. The first field observations of this little-known taxon were made in the 1990s and our data therefore provide the first published information on its natural history, including breeding biology, behaviour and vocalizations, as well as a new locality. As very little information has appeared in the literature concerning the identification of this species, we present notes on its plumage and habits. Remarks concerning the species's conservation prospects and the importance of the remaining forest in the vicinity of the type-locality for other threatened bird species are made.

The island of Santa Catarina lies in the Atlantic Forest Domain of southern Brazil, one of the most threatened ecosys tems on the planet. It holds a wide variety of habitats, ranging from sand dune ‘restingas’ to mature rain forest. We report, for the first time, a survey of the bird species and their conservation status for the different habitats present on the island. We recorded 269 bird species of 54 families (25 species were seabirds). More than 50% (140) of the total number of species were residents or probable residents, 20% (58) were visitors and a relatively high number of species (61, 23%) had indeterminate residential status. Nearly 15% (35 species) of the 244 landbird species observed were endemic to the Atlantic Forest. Habitat specificity was recorded for 40% (97 species). We recorded one Endangered (Solitary Tinamou Tinamus solitarius), one Vulnerable (White-necked Hawk Leucopternis lacernulata), and three Near-threatened species (Azure Jay Cyanocorax caeruleus, Azure-shouldered Tanager Thraupis cyanoptera, Black-backed Tanager Tangara peruviana). We also recorded six locally threatened species that we predict will become extinct in the near future. The future for the birds of the island is uncertain, especially for habitat specialists, due to habitat loss for resort developments, and a lack of concern by the government and local people.

SummaryAn annotated compendium of all those bird species known to have occurred in the lowland “Man and Biosphere” Beni Biological Station (B.B.S.) reserve is provided. Previous checklists are reviewed, together with sightings accumulated over the 1992–1995 period during which approximately 70 new species have been added to the reserve inventory, bringing the total to 478. Occurrence across the 12 delineated habitats, relative abundance and sighting documentation are given for each species. The avifauna of the B.B.S. is mixed biogeographically; in addition to a substantial component of lowland birds widespread throughout South America, it is composed of Amazonian, cerrado and chaco elements also. Representation from the Bolivian Yungas is minimal. Significantly, no less than four threatened and 15 near-threatened species have occurred, including the little known Bolivian endemic Unicoloured Thrush Turdus haplochrous, and the enigmatic White-winged Nightjar Caprimulgus candicans, known until recently only from Emas National Park (Brazil). Short accounts are provided detailing records of all of these species. Birds of the reserve core, consisting largely of humid tropical forest formations inundated during the austral summer, appear not to be subjected currently to any serious environmental degradation, although some subsistence clearance by Chimane Indians in the northern reaches of the reserve gives some cause for concern. Of much greater import, however, are changes occurring outside the confines of the B.B.S. These include increasing urbanization immediately to the west (and associated road upgrading) and forest fragmentation to the south brought about by logging. The latter is especially worrying because linkage of the B.B.S. forest block to surrounding forest is already physically tenuous, and therefore it is imperative that future logging activities be geared to minimize isolation occurring and the damaging restriction of gene flow. Monitoring in rainforest immediately south of the reserve should become routine to warn of putative avifaunal impoverishments. Extensive surveying of the 2,500-ha El Porvenir éstancia (savanna and related forest islands) due to be assimilated shortly into the B.B.S., which constitutes less than 2% of the area under consideration, has shown that it is used by no less than three threatened and up to nine near-threatened species. In the absence of data relating to other savanna areas (c. 15%) at present, the exact status of each species at the B.B.S. remains imprecise and begs for further research to be undertaken. Unfortunately, present management of the El Porvenir savanna is not conducive to the long-term maximization of populations of these species, several of which have local strongholds in this part of Beni. We recommend that the current policy of cattle ranching adopted by this éstancia should cease or be reduced dramatically, to minimize grazing and trampling damage, and that measures should be taken to reduce incursions of fires started wilfully in neighbouring properties. The Academia Nacional de Ciencias de Bolivia, which administers the reserve, should be encouraged to safeguard and enhance the savanna complement further by ensuring that the impending ratification of El Porvenir proceeds as quickly as possible, and by purchasing additional tracts of land to the south of the present southern reserve boundary, where feasible. Such actions should not only secure the future of the biota of the savanna habitat within the B.B.S. but also should ameliorate the degree of isolation which has occurred already by preserving the “curiches” (former river beds) and forest islands which act as access corridors for forest-dwelling and other birds.

AbstractThe Diptera occurring in various kinds of bird nests were investigated in the Japanese island of Hokkaido from 1985 to 1989. A total of 4623 Diptera, consisting of 23 species of eight families (Anthomyiidae, Fannidae, Muscidae, Calliphoridae, Heleomyzidae, Sphaeroceridae, Sepsidae, and Stratiomyiidae), was reared from 69 natural nests of 13 bird species of eight families (Strigidae, Picidae, Paridae, Sittidae, Sturnidae, Ploceidae, Laniidae, and Columbidae). Of 23 species of flies reared, 12 were new records from bird nests. An ectoparasite of birds, Protocalliphora maruyamensis Shinonaga and Kano, frequently emerged from the nests of hole-nesting birds of Paridae, Sturnidae, and Ploceidae, but it did not emerge from the nests of the hole-nesting birds Picoides major and P. minor of Picidae. The nests of Streptopelia orientalis yielded the most species of flies (12). Myospila meditabunda (Fabricius) and Mydaea urbana (Meigen), whose larvae are predacious, proved able to live in the bird nests. Among the scavengers, Potamia littoralis (R.-D.) was the most dominant and occurred in the nests of nine of 10 hole-nesting bird species. Sphaerocerid, sepsid, and stratiomid flies occurred in the nests of S. orientalis in which large quantities of bird feces had accumulated. The factors concerning the occurrence of flies in the nests are discussed.
